Bluefin Tuna Steak with Togarashi

Blackstone Seared Bluefin Tuna Steak

Bluefin tuna is a special treat, so if you get your hands on some it is important to get the prep right. Fortunately, this is one of the easiest recipes EVER, and it is fast too. The biggest enemy of great tuna is overcooking it, so use a light hand, a hot cooking surface, and prepare to be amazed.

This recipe works really well with other types of tuna fillets also, so bring out the Yellowfin, Bigeye, and Albacore too.

What is Togarashi?

Togarashi (aka shichimi) is a Japanese 7-Spice blend that is spicy and contains the following ingredients:

  1. Red Chili Peppers
  2. Sichuan Peppercorns
  3. Black Sesame Seeds
  4. White Sesame Seeds
  5. Ground Ginger
  6. Ground Orange Peel
  7. Dried Seaweed

We love Togarashi here and use it for a lot of different dishes. Check out our Togarashi Pork Tenderloin, Togarashi Smoked Salmon, Blackstone Togarashi Zucchini Spirals, and the Grilled Salmon Togarashi Rice Noodle Bowl.

In Japan, it is used as a table condiment much like we use salt and pepper. My favorite brands tend to be the ones with no English on the packaging. I use this one and this one most often. The Spice Guy also makes a great domestic blend too.

Season the tuna steak liberally with the Togarashi and salt.


Lay down a thin coat of oil and sear the tuna steak for 30-45 seconds per side.


Slice the tina into thin pieces. Drizzle with wasabi mayo and sriracha mayo (if desired) and serve with high quality soy sauce for dipping.

Togarashi Tuna Steak FAQ

How do you store leftovers?

Try not to HAVE leftovers. This is an expensive piece of meat, and like all fish, it is best eaten immediately after you thaw and cook it.

What’s the best way to reheat leftovers?

Don’t! If there are any leftovers that you don’t eat right away, just eat them cold and thank me later.

Are there any substitutions for Bluefin Tuna?

Yes! You can also use Ahi, Yellowfin, or Bigeye tuna for this recipe too, and it’ll be awesome.
